Re: performance for huge table

Thanks  Matthew  for your  fruitful  reply   :-),

Now my problem  is  I have to start calculation for my logic of  1 / 0   from third field  which name is  FIELD  here and not from the first field,

I have to start calculation from Field on 3rd number in above code   till the field yyvloctype  which is on 25th number   and update all calculation on 26th priority  field

so how can I  control that immediate after  loop and before Do . ? because in loop it bring all  fields in one row .

LOOP AT it_tab ASSIGNING <is_tab>.

????????????

     DO 30 TIMES.
       ASSIGN COMPONENT sy-index OF STRUCTURE <is_tab> TO <fs_value>.
       IF sy-subrc IS INITIAL AND <fs_value> IS NOT INITIAL  .
         CONCATENATE <is_tab>-priority '1' INTO <is_tab>-priority.
       ELSEIF <fs_value> IS INITIAL OR <fs_value> EQ '*'.
         CONCATENATE <is_tab>-priority '0' INTO <is_tab>-priority.
       ENDIF.
     ENDDO.
